Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

Limnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Fluorenone and Fluorenemalononitrile‐Tethered Conjugated Microporous Polymers for Efficient CO2 Uptake and Rhodamine B Removal

Macromolecular Rapid Communications, EarlyView.
TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.

Thermal and Morphological Analysis of Biocomposite From Multilayer Plastic Waste and Oil Palm Empty Fruit Bunch Fiber

Macromolecular Symposia, EarlyView.
ABSTRACT Oil palm empty fruit bunches (OPEFB), a byproduct of the palm oil industry, have great potential in the circular economy, particularly for composite material production. Multilayer plastic waste from the bottled water industry presents significant environmental challenges.
